I found FNR by way of desperation. I was constantly exhausted, suffering with joint pain, anxiety, unexplained weight gain and crippling IBS for over 20 years. Everything kept getting worse regardless of what doctor's prescribed. I reached a breaking point when I found the team at FNR. I am now 90 days through the program and have experienced 99% health improvement. I no longer have joint pain, I'm not exhausted anymore, I've lost 20lbs, my anxiety has significantly lessened to the point of voluntarily stopping all anxiety medication and the best part - my IBS is FINALLY manageable and barely noticeable. That is a statement that I never thought possible. I was suffering multiple attacks a day every single day down to 2 in the last 3 months. I highly recommend the FNR team and approach to anyone looking to make a lifestyle change. It's worth the time and financial investment for a new...

For several years, I struggled with autoimmune conditions and hormone imbalances that left me exhausted, discouraged, and unsure of what the future held. Despite trying countless strategies and spending a great deal of money on different approaches, nothing truly helped me get to the root of my health struggles.

That changed when I found FNR. From my very first interaction, I could tell this was not just another health practice. Lindsey, the wellness concierge, guided me through onboarding with such warmth, clarity, and professionalism that I immediately felt at ease. She was always just a phone call away, consistently greeting me with her pleasant, authentic disposition every time I walked through the door. These first impressions set the tone for everything that followed.

Jennette, the founder of FNR and my RDN, went far beyond surface-level care. She asked...

If you are looking for a Functional Nutrition approach for your health journey, there is no better place than Functional Nutrition Resources. I could not have gotten to where I am today without them. What is so special about FNR is that they walk you through every single step - through all the positive things and all the challenges. Every single change, question or win…they are there. You do not have to go at it alone, and that really makes a difference. For years, I had been struggling, and everything that I had tried before FNR was not solving my issues. I felt so alone and lost. When people would ask how I was feeling, I could hardly convey what was going on, because I did not know what was truly going on myself. I was at the point of helplessness, like I would never have a normal life being able to do the things I wanted to do (and should have been able to do in my 30’s). When I...

In 2003, I was diagnosed with osteoporosis at age 54 that got progressively worse over the next several years. In 2017, I was diagnosed with an underactive thyroid gland, started having constant bouts of IBS-D, brain fog, joint pain, had constant UTIs and brain fog, and just felt lousy most of the time. In 2018, my new primary care physician ordered a colonoscopy and an endoscopy. The endoscopy revealed that I had gluten sensitivity. No one in my family has ever had celiac or gluten sensitivity. So, I stopped eating gluten. I learned that my gluten sensitivity was the likely cause of my thyroid issues (which my new doctor told me was Hashimoto’s thyroiditis). I always had difficulties digesting dairy, so I also stopped eating dairy. The diarrhea continued into the fall of 2018, so my new doctor suggested that I make an appointment with FNR. I signed up for their help at my first...
